OKI have LS-QVL with Fw 1.71 4 x2TB disks RAID 10.All running well until power outage a few days ago.Disk 2 - Error - no disk info (ie it doesn't think there is a disk 2).Disk4 - a few errors but disk info showing....rebuilt array cleared these on disk 4......disk 2 remains a problembutAlthough the array is degraded I can read all my data Dodged a bullet there.

Power down and put in a BRAND NEW 2TB disk. Now it starts up, reads the disk info AND says error on disk 2 and WONT mount the array at all (unformatted). So cant access the data at all. Take new disk out and restart - I can see data again on degraded array.So - I *thought* that just installing a new drive in the right slot was enough to kick off a format/repair/rebuild but obviously not.Hitting rebuild array - lots of warnings - but when process finishes exactly the same - error on disk 2 (the new one) and array not mounted.

Do new disks have to be formatted BEFORE they are added to an existing array?

SoThe manual is wrong (as many have pointed out). It doesn't *just work*

To be clear do I need to:a) remove the failed drive 2 (which has the new disk in it) from the arrayb) format the new disk (outside of the array)c) add to the arrayd) rebuild the array

From what I can tell from multiple posts that seems like the approach but I want to check before I do something stupid

1. make a backup of all needet data2. delete all partitions on the new disk3. read out the old disk and set MBR or GPT on the new disk4. format the new disk with the linkstation5. remove the new disk in the software, do not remove the hardware6. the removed drive should be able to add to the degraded raid

The problem I have is formatting the new disk.When I start the linkstation with the new drive in slot 2 (instead of the failed one) the system shows it in the array as status 'error'The *only* option I have for that disk not greyed out is 'remove'.So I choose remove.

I enter the security code and the system tells me its removing the disk from the array....but......after process has finished the disk is not removed from the array. Its still there showing 'error' and I cant format it and the array is unusable.I've tried 3 times with same result.

Any thoughts as to how I get that disk out of the array for formatting?Thanks

a) tried to use the web admin to 'remove' the new disk - so I could re-add it to the arrayb) it didn't seem to do anything (new disk still showing as 'error' in array)c) knowing I have 4 good disks (3 old + 1 new) I hit rebuild arrayd) Process started but has stuck at '40%' for over 2 hours. Is this normal?

logging into the web admin I get the message:

"Cannot change all of the configurations until changing Raid Array is completed. Also share folder service is not working."

but - all the data is still available so the array IS running in degraded state and can be accessed by shares

Does anyone know how long a RAID rebuild should take? Hours? Days? Months?

I now have no control over the unit without pressing the power button - which I don't really want to do if it really is rebuilding.........

PS it's *really* annoying to have to wait for posts for get 'approved' for this forum - especially when you are in a non-US timezone

update 3 - just really for anyone else finding this thread and having a similar problem.

As far as I can tell the array IS rebuilding. It is just very slow. The web interface is useless in providing feedback.It basically seems to be hung which is not very reassuring.But going into the LS through SSH and running /proc/mdstat a few times I can the numbers incrementing each time.

...and as you can see its almost 47% done after nearly three hours. I have a 4TB array half full (2TB) so that gives you an idea how long it takes.According to the stats above its projecting nearly 6 hours to finish.So I does take a long time and I need to be *patient*
